So on the night where Bedbug threatens to stuff you if she wins, losing your last HP to her just gets you locked on a black screen. You can open the menu but it just says black forever.
Also in the maze before that, the first dozen times I tried to get through it the pattern of the row of 3 jumping hands on the left all jump in and out of the 'hallway' was messed up so it was impossible to get through undamaged. And it happened again in the soap sliding section.
